Abstract

A liquid dispensing apparatus comprising a container portion, a receiver portion, and a grip portion. The container portion includes a first opening, a second opening, and a third opening. The first opening comprises a trap door valve. The second opening comprises a vent valve attached to a trigger located in the grip portion. The third opening is in liquid communication with a liquid ejection system.

What is claimed is: 
     
         1 . A liquid dispensing apparatus, comprising:
 a container portion, a receiver portion, and a grip portion, wherein the container portion includes a first opening, a second opening, and a third opening;   the first opening comprising a trap door valve;   the second opening comprising a vent valve attached to a trigger located in the grip portion; and   the third opening being in liquid communication with a liquid ejection system.   
     
     
         2 . The liquid dispensing apparatus of  claim 1 , wherein the trap door valve further comprises a flap and a structural element capable of supporting the flap when the container portion contains liquid. 
     
     
         3 . The liquid dispensing apparatus of  claim 2 , wherein the flap is a flexible material. 
     
     
         4 . The liquid dispensing apparatus of  claim 3 , wherein the flexible material is magnetic and the first opening includes a seal element that is magnetically attracted to the flap. 
     
     
         5 . The liquid dispensing apparatus of  claim 4 , wherein the flap is a rigid material. 
     
     
         6 . The liquid dispensing apparatus of  claim 5 , wherein the flap includes a magnetic portion and the first opening includes a seal element that is magnetically attracted to the magnetic portion. 
     
     
         7 . The liquid dispensing apparatus of  claim 1 , wherein the vent valve further comprises an inner portion located within an outer portion, the inner portion capable of actuating between a closed position and an open position. 
     
     
         8 . The liquid dispensing apparatus of  claim 7 , wherein the trigger is attached to the inner portion of the vent valve, such that displacement of the trigger will actuate the inner portion between the closed position and the open position. 
     
     
         9 . The liquid dispensing apparatus of  claim 8 , wherein both the trigger and the inner portion of the vent valve are in contact with a single spring, such that the default position of the inner portion is the closed position. 
     
     
         10 . The liquid dispensing apparatus of  claim 1 , wherein the liquid ejection system further comprises at least one ejection outlet. 
     
     
         11 . The liquid dispensing apparatus of  claim 10 , wherein the liquid ejection system comprises a pump. 
     
     
         12 . The liquid dispensing apparatus of  claim 11 , wherein the pump is a single-acting positive displacement pump and includes a plunger. 
     
     
         13 . The liquid dispensing apparatus of  claim 12 , wherein operation of the pump forces air into the container portion. 
     
     
         14 . The liquid dispensing apparatus of  claim 13 , wherein depression of the trigger portion opens a third valve, enabling the liquid and air in the container portion to escape through the at least one ejection outlet. 
     
     
         15 . The liquid dispensing apparatus of  claim 12 , wherein operation of the pump forces liquid from the container portion through the at least one ejection outlet. 
     
     
         16 . The liquid dispensing apparatus of  claim 1 , wherein the receiving portion includes at least one illumination device capable of emitting light. 
     
     
         17 . The liquid dispensing apparatus of  claim 16 , wherein the at least one illumination device includes an electrical push button. 
     
     
         18 . The liquid dispensing apparatus of  claim 1 , wherein the receiving portion includes at least one gun rail. 
     
     
         19 . A method for rapidly filling a tank with liquid and expelling the liquid, comprising the steps of:
 submerging a liquid dispensing apparatus at least partially into a liquid source,
 wherein said liquid dispensing apparatus comprises a container portion, a receiver portion, and a grip portion, wherein the container portion includes a first opening, a second opening, and a third opening;
 the first opening comprising a trap door valve, 
 the second opening comprising a vent valve attached to a trigger located in the grip portion, and 
 
 the third opening being in liquid communication with a liquid ejection system; 
 wherein pressure from the liquid source pushes the trap door valve into an open position and a portion of the liquid source enters the container portion; 
   squeezing the trigger, wherein the vent valve moves into an open state, enabling air to escape the container portion;   releasing the trigger, wherein the vent valve moves into a closed state, sealing the container portion and preventing the air and the portion of the liquid source in the container portion from escaping said container portion; and   surfacing the liquid dispensing apparatus from the liquid source.
